摘要
预制梁桥的主梁通常采用架桥机或吊车架设,当跨越河道桥梁上方受低空高压线限制时,上述架设方法均不适用.本文采用架桥机与地面运输系统相结合的方式,能有效解决条件受限状况下的架梁问题,可为同类工程提供参考.
Abstract
Bridge erecting machines and cranes are generally used for installing the main beams of prefabricated bridges,however,these methods are not applicable for bridges that cross rivers and are restricted by low-altitude high-voltage lines.This paper combined the bridge erecting machine with the ground transportation system,which can effectively solve the difficulty of erecting girders under restrictions,providing a reference for similar engineering.
